“[Battery testing…] these have to be the worst results I’ve ever seen.” High internal resistance. Since high-amperage cycles whilst still under warranty, melting terminals, erratic discharg curves that mostly collapse.

“The battery will be determined to be defective if it fails to deliver less than 80% of its rated capacity during the warranty period” -Battleborn warranty in 2022. Look up warranty today and see what changed. Another excerpt from Battleborn documentation: “Cycle life varies widely depending on rate of charge, after 3000 cycles you will have approximately 75% battery capacity remaining if charging and discharging at a 1C rate. Most applications are less 0.5C rate which means you will get more cycles in most applications.”
